HISTORY OF THE CITY OF NEW YORK.

[p.426] ... In 1720, some years hefore Watt was born, Joseph Hornblower was conspicuous in the superintendence and construction of steam-engines, then called fire-engines, after the model of Newcomen, being simply atmospheric engines with a single cylinder. He had seyeral sons: Jonathan, born in 1717, and Josiah, born in 1729, became eminent. engineers. The Hornblowers, father and sons, subsequently removed to Cornwall to pursue their business, where they were engaged in putting up engines from their first introduction into the mines in 1740. The success of these engines in the mines of Cornwall induced Colonel John Schuyler to import one for pumping water from his copper-mine on the Passaic River, near Newark, New Jersey - a mine rich in ore, but which had been worked as deep as hand and horse power could clear it of water. His correspondents in London purchased one of Hornblower's engines, and persuaded Josiah Hornblower, then only twenty-four years of age, to proceed to America and superintend its erection. He arrived in New York in September, 1753, and occupied the best part of a year in building an engine-house and getting it into successful operation. This was the first steam-engine ever erected on the continent, of America; and it was when Watt was but seventeen, and his inventions simply marvels of the future.*
 
    Young Hornblower expected to return to England as soon as his work was accomplished. But in the neighhorhood of the Schuyers lived Colonel William Kingsland, grandson of Isaac Kingsland, the founder of the Kingsland family in America - whose wife was Mary, daughter of Judge William Pinhorne, of the reader's acquaintance in the early pages of this work. Hornblower became a frequent visitor at the Kingslands'. It is the old, old story of romantic love. In two years his destiny was sealed. He married the beautiful Elizabeth Kingsland, then twenty-one, and became an American.** He afterwards not only superintended the engine whenever his skilled services were needed, but after 1760 for [p.427] several years worked the mines, and people came from all the country round to see the wonderful machine.

    Meanwhile his brother Jonathan remained at Cornwall, where he died in 1780, several of whose sons were educated as engineers, and produced many useful and notable inventions. Jabez and Jonathan were the most conspicuous among them. Jabez was employed to superintend the erection of steam-engines in Holland and in Sweden. Jonathan, inventor of a double-cylinder high-pressure engine, was one of the most active and formidable of the rivals of James Watt; and his engine is the one now principally used by ocean steamers, as, requiring only about half the coal of the Watt engine, it is better suited for long voyages. A litigation ensued, Hornblower's invention being pronounced an infringement of Watt's patent, which also had two cylinders, though one of them was only used as a condenser; and while nothing was ever alleged to the dishonor of the Hornblowers in this controversy, public favor clamored in behalf of Watt, and they were defeated.
